Question

Rationalize the denominator 1/√3−1

Answer 1

Solution:

$\frac{1}{ \sqrt{3} - 1 } \\ = \frac{1}{ \sqrt{3} - 1} \times \frac{ \sqrt{3} + 1}{ \sqrt{3} + 1 } \\ = \frac{ \sqrt{3} + 1}{( \sqrt{3})^{2} - (1)^{2} } \\ = \frac{ \sqrt{3} + 1 }{3 - 1} \\ = \frac{ \sqrt{3} + 1}{2}$

Answer:

$\frac{ \sqrt{3} + 1}{2}$

Answer 2

Multiply the fraction by the (denominator/denominator)
Which is equals to 1.

1/root3-1 * (1/root3-1) / (1/root3-1)

Now you have root3-1 / 2
